The flanges staples 15, which pass around the furring strips of a fastener so supported are disposed in interwith their ends twistedtogether after piercing laminate relation to the anges of the support. the libre-back and passing through openings in In assembling the parts of the insulator device,

the metal lathing. a strip 24 of Wool felt, asbestos felt, or other 55 sound-deadening material is twice doubled upon itself so as to iill the space between support portion 17 and fastener iiange 21, the space between the latter and support flange i8, and the space between flange 18 and fastener flange 22. The deadening strip 24 will then have `the shape of the letter S and will therefore: underlie the edge of fiange 21 and overlie the edge offiange 18. Thus all parts of the metallic members of the insulator will be separated by sound-deadening material, as will be apparent by inspection of Figs. 2 and 3.

Having proceeded so far in the construction of a plaster covered wall, the addition of furring strips and metal lathing may be quickly and v easily accomplished. Ordinarily when mounting insulators for supporting furring strips in spaced relation to a base wall, it is necessary to secure the insulators to the base wall in strict alignment in the direction of the lengths of the furring strips, in order that the latter may be fastened to the insulators. And as the said insulators are generally immovably mounted on the base wall, the alignment of the insulators requires mechanical skill and considerable care. Thus much time is, lost merely in securing the insulators to the base walls in their predetermined positions.

This disadvantage is entirely absent in the installation of my device. Obviously itis a simple matter to secure the supports to the base wall in substantially horizontal position. 'Ihen the desired number of fasteners may be hooked over a support and adjusted along the support to approximately their proper positions. The constand vertically, wherefor a fastener on each suplso , port to which the furring strip is -to be secured ji lo will be vertically aligned with each other fastener which is to support the strip.

In securing my furring strips to the fasteners I lay a tie-wire 25 across the strip, pass the ends of the wire behind the lugs 23 of the fastener, then bringthem together in front of the strip and twist them together to the desired tightness. While any form of furringstrip may be used, I preferably employ a channeled strip having its web placed ilat against the fastener and its flanges in position to be engaged by the metal lathing. This arrangement is shown in Figs. 1 and 2.

From the `foregoing description it will be obvious that not only is the plaster supporting construction light and inexpensive, but the ease with which it may be built up will be readily understood. Also, it is to be noted that any movement of the plaster wall relatively to the base wall due to expansion or contraction will not harmgthe structure. Slight outward movement of the plaster wall will be accommodated by the resiliency of the overlapping flanges of the insulator members, while movement in the planel tageous facility of erection as compared with my preferred embodiment but would result in economy of material and somewhat reduce the thickness of the completed wall structure.

It will be seen that there is provided a construction of an essentially practical nature in which the several objects of this invention are attained.

As many possiblev embodiments may be made of the above invention without departing, from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
